4.3 out of 5
Useless All the Months just blend together

I don’t even understand somebody spending the time to put this on CalendarZ Store you can’t separate the month it’s just one big long sheet with no separation , the month is only written in a different color ink in the background . It’s almost like they’re trying to save paper by starting the next month consecutively after the last day of the prior month. As I said no separation one continuous line of days

Lost a lot of info

On Jan 1 I started entering places and mileage for every trip I made to help dogs. I entered the name of the dog where I picked it up from and took it to followed by the mileage. Perfect, exactly what I needed. In April I needed to refer to a date I took a dog to transport. I wasn’t sure which week so went to look. GONE!!!!! EVERYTHING I had entered prior to one month before was gone. However every Holiday, Every Presidents Birthday or anything else normally pew marked on a calendar was still there.
What I lost cannot be replaced and Zi tried everything including going to the Apple Store to see if I could retrieve it. Nope, can’t be done.
I would pay to have a Calendar that I could refer back to for as long as I need to.
I’m extremely disappointed in the usefulness of this calendar. I guess it works great for the future but it does not work to document times or appointments you have had in the past.

Everything I depend on GONE!

I opened my calendar today to see when my cats next chemotherapy treatment was but received a message that the developer needed to update for my version of IOS. ???? I’ve done everything to retrieve years of information but can’t!
If the developer can help me get years of dates, appointments, birthdays, and very important information, I would definitely appreciate it. WARNING TO USERS… take screenshots of anything you put on this calendar because you will suddenly find it has disappeared!

Can’t change settings

Just isn’t for me-can’t change the settings and have the word “February” as a title and I have two friends that even can’t get it changed. We have backed the word out and it still shows even when we save. I need one month to show, but it shows the next month after—again-not for me...

Great App

Please fix! - my holiday events color keeps changing to purple even though i have set it to yellow so many times.

Also pls pls remove the vertical time tick lines that show up on the event/reminder list preview when you click on a certain date. Its so confusing and it looks horrible. Pls pls fix this.

This is by far my favorite calendar app. I would love to see the above issues fixed and more features and customization options added on 😊

Thank you!

Repeats

I would like CalendarZ to offer a “every 3 week” possibility. I clean houses and have many customers that have cleanings every three weeks.I manually have to enter each person each month which is time consuming.

Good Simple App

I like the ease and simplicity of keeping track of my appointments and I use CalendarZ frequently to check times and dates. I wish the past entries didn’t disappear! It should be an easy fix. Other than that, I would have given 5 stars.

Activity

Deserves 5 stars but wish it kept the activity for previous months as I mark start dates and when I need to go back to retrieve theses dates that I input on my calendar they are gone..... please fix

1 area to improve!

I love CalendarZ. I just wish my events didn't disappear when the month is over. Sometimes I want to look back to see what I did the previous month. Would receive 5 star if this feature was included.

Works

This would be a five rating if one could increase the font. I tried but then the quick notice is completely jumbled. Maybe someone knows how to increase all the print….then I would be very happy to give it a five.

Great!

This is a fantastic app! I love the calendar and the ability to customize it. Except I wish it had more color options and it was easier to maneuver around, such as being able to delete things or even just change things around.

Intuitive

Very intuitive.
Only problem is I cannot get it to stay on my Apple Watch face for today’s events (next days always good). I suspect it’s an apple problem since it is approved for apple watches.

Easy to read

I like being able to see what’s booked for the month. The iCal just shows a dot and I have to open the day to see what the dot is for. With this I can get a quick view of what’s coming up and it also shows my reminders that I can easily check off. I love it thus far.

Love this calendar

I’ve been using this calendar for at least 5 years. I love the simplicity of it and it shows me months, not weeks or days. I need to always see the big picture in a monthly format. I think it had a name change quite a while ago and I don’t know why, but it still has all the same functions.

Great app

My wife and I share calendars and work related reminders. It makes it very convenient being to check each other's work load to plan fun time with each other. 😉👌

Please add horizontal scrolling in month view

Just like the title says. This calendar is pretty much perfect except I would like the ability to horizontally scroll in month view. That’s all it needs!

I use it all day every day!

I absolutely love CalendarZ! I can add all of my bills and my work schedule and it can update months ahead of time and repeat. I love that I can pictures and directions on events-helpful with parties. I especially love that I can use all the different colors if I would like to. Are usually do not leave any reviews on apps but this one is especially helpful to me in my life and I am very thankful!

By far the BEST

This is my favorite calendar app, and I’ve tried them all. Second best is Fantastical, however the month view on Fantastical needs to be as good as CalendarZ.

Been using for over 2 years.

Probably the best, most functional, calendar of it’s kind that I’ve used. Good for both personal and business.

Best I’ve Tried .. & I’ve Tried many

CalendarZ is the perfect combination for my needs
It has a screen long monthly view that displays all your events and the best part about it for me is that it also displays all my tasks. As someone who relies heavily on their calendar for appointments and to-do lists this is a major point in my book I love that I can check off the tasks as I complete them right on the calendar without having to jump to a different screen or page. For those who can’t see the previous appointments on their calendars after the last couple of weeks, this is an apple setting not a calendar z app issue. To fix this just go to settings-calendars- sync and select ALL EVENTS. This will bring back all appointments from previous months.
I paid the .99 for the ads free version and i think it was worth it.
